在之前的一篇文章中，我们介绍如何安装并使用odb工具，请见http://blog.csdn.net/post_yuan/article/details/54631881
在另外一篇文章我们也通过几个简单的例子介绍如何用odb进行基本的数据加载、抽取、转换工作，请见http://blog.csdn.net/post_yuan/article/details/52671874

现在我们考虑一下如果原始数据文件中有中文，使用odb加载会怎么样，

1 创建测试表

>>create table test_chinese(a int, b varchar(20) character set utf8);

--- SQL operation complete.
>>showddl test_chinese;

CREATE TABLE TRAFODION.SEABASE.TEST_CHINESE
  (
    A                                INT DEFAULT NULL NOT SERIALIZED
  , B                                VARCHAR(20 CHARS) CHARACTER SET UTF8
      COLLATE DEFAULT DEFAULT NULL NOT SERIALIZED
  )
 ATTRIBUTES ALIGNED FORMAT
;

-- GRANT SELECT, INSERT, DELETE, UPDATE, REFERENCES ON TRAFODION.SEABASE.TEST_CHINESE TO DB__ROOT WITH GRANT OPTION;

--- SQL operation complete.

2 创建测试文件

[trafodion@n12 bin64]$ cat test_chinese.txt
1,我爱中国
2,你好中国
3,安徽卫视

3 odb加载测试文件

[trafodion@n12 bin64]$ ./odb64luo -u trafodion -p traf123 -d traf -l src=test_chinese.txt:tgt=trafodion.seabase.test_chinese:fs=,:truncate

4 trafci查询加载数据

SQL>select * from test_chinese;

A           B
----------- --------------------------------------------------------------------------------
          1 ±
          2  
          3 è§

--- 3 row(s) selected.

从上面结果可以看出，默认情况下odb插入中文，通过trafci/jdbc查询乱码，这可以通过以下方法解决。

1 在odbc.ini配置中添加ClientCharSet = UTF8

[trafodion@n12 bin64]$ cat /etc/odbc.ini
[ODBC]
AppUnicodeType=utf16

[traf]
Description                 = Trafodion DSN
Driver                      = Trafodion
Catalog                     = TRAFODION
Schema                      = SEABASE
DataLang                    = 0
FetchBufferSize             = SYSTEM_DEFAULT
Server                      = TCP:10.10.11.12:23400
SQL_ATTR_CONNECTION_TIMEOUT = SYSTEM_DEFAULT
SQL_LOGIN_TIMEOUT           = SYSTEM_DEFAULT
SQL_QUERY_TIMEOUT           = NO_TIMEOUT
ServiceName                 = TRAFODION_DEFAULT_SERVICE
ClientCharSet               = UTF8

2 重新加载数据

3 trafci查询加载数据

SQL>select * from test_chinese;

A           B
----------- --------------------------------------------------------------------------------
          1 我爱中国
          2 你好中国
          3 安徽卫视

--- 3 row(s) selected.
